2. Description of the Related Art

Korean Patent No. 1686547 (issued on Dec. 8, 2016 and entitled “Nonslip Sports Sock”) discloses a nonslip sports sock. As shown in FIG. 6, the nonslip sports sock includes: a sock body 100 configured such that the inner circumferential surface thereof surrounds a foot 1 of a user; and a nonslip sheet 200 configured such that the nonslip sheet 200 includes a wet urethane sheet in which cells having a roly-poly shape with a wide lower portion and a narrow upper portion and a vertical column shape are formed by applying and coagulating a polyurethane solution onto a base material 400, cells 210 having an inverted roly-poly shape with a wide upper portion and a narrow lower portion are attached to the inner circumferential surface of the bottom of the sock body 100 in a state in which the sock body 100 has been turned upside down with the base material 400 separated, amorphous nonslip depressions 220 having a diameter of 0.1 to 2 mm are formed on the upper surface thereof which comes into contact with the sole 2 of a foot of a user, and the nonslip depressions 220 are configured to communicate with the top portions of the column cells 210. The base material 400 includes a plurality of convex portions 410 configured to protrude upward from the surface of the base material 400, concave portions 420 formed among the convex portions 410, and a separation promotion agent 430 applied only onto the convex portions 410 of the base material 400. The nonslip depressions 220 are formed in such a manner that urethane coagulated onto the concave portions 420 to which the separation promotion agent 430 has not been applied is torn when the base material 400 is separated from the wet urethane sheet, auxiliary depressions 230 are formed in the portions corresponding to the convex portions 410 of the base material 400 on the nonslip sheet 200 in response to the removal of the base material 400, the base material 400 is formed by weaving warps and wefts made of multi-filaments, and a plurality of troughs 231 is formed in the auxiliary depressions 230.

The conventional technology is configured such that the wet urethane sheet is turned upside down so that the cells are inverted such that the cells have an inverted roly-poly shape with a wide upper portion and a narrow lower portion, in which the diameter of the portions that come into contact with a foot is larger, based on the fact that the cells having a roly-poly shape with a wide lower portion and a narrow upper portion are formed on the wet urethane sheet, and the upper portions of the cells are formed to communicate with the outside. It is asserted that the conventional technology has an excellent effect even in an environment including sweat and water by preventing a water film phenomenon in such a manner as to act as a reservoir for temporary storing sweat generated from a user's foot. However, the conventional technology has a fundamental defect in that a fabrication process is complex because the configuration of the conventional technology is complex.
